Distinguish between: Dominant and Recessive character.

The characters that

 are expressed in F1
generation are dominant.

The characters that are

 not expressed in F1
generation are recessive.

It is expressed in presence

 of dominant as well
as recessive allele.

 e.g. Tt, TT = tall.

It is expressed only 

when both the recessive
alleles of a gene are 

present. e.g. tt= dwarf

In pea plant, tallness 

and red flowers are
dominant characters.

In pea plant, dwarfness 

and white flowers
are recessive characters.

Dominant character can 

express in both
homozygous as 

well as heterozygous condition.

Recessive character

 can be expressed only
in homozygous condition.
